Simchat Torah celebrates the end (and the beginning) of the annual Torah-reading cycle. Just as we reach the concluding section of Deuteronomy (the fifth book of the Torah) do we start over once again with Genesis (the first book of the Torah).
Only in the 11th century did the 9th day after the beginning of Simchat Torah take on both the name and the festive ritual of what we now recognize as Simchat Torah. An annual holiday of this nature implies a one-year cycle of Torah reading, but such was not always the case. In ancient Palestine, Jews followed a triennial, or three-year, cycle of Torah reading. The one-year cycle was a custom of the Babylonian Jewish community. It was not until the 8th century that the great majority of Jews adopted the annual system. Simchat Torah as an annual observance, then, emerged only after the divergence in customs over the Torah reading cycle was resolved.
Simchat Torah is a joyous celebration during which the Torah scrolls are taken from the ark and carried by congregants around the synagogue seven times. During these seven circuits, or hakafot, those not carrying Torahs often will wave brightly colored flags and sing Hebrew songs.
In Israel, Simchat Torah is observed on the one and only day of Sh’mini Atzeret, but for most Israelis it is just another day of Sukkot vacation. In many towns, public celebrations are held on the night after Simchat Torah. Known as hakafot shniyot (second processions), these events are simulations of Simchat Torah dancing and singing, but with professional musicians and electronic amplification. They are, in effect, “reruns” of Simchat Torah, designed to allow the public to enjoy the holiday without any of the restrictions or accoutrements of religion. These public festivals are usually popular and crowded.
